The flashings had to be installed today and the windows fitted and nailed because on thursday, the glasziers were coming in to fi the glass. So cam pulled a bunch of us a side and showed us how to cut and install a flashing for a window sill. Once done, teams of us went off and done our own.
-measure 45mm in and mark all the way down
-cut the 2 angle's (cutting the bottom strand off)
-using the bending pliers, set the grip and bend so the cut pieces are nice and straight when butted into eachother
-cutting the tips on a slight angle so they wont catch when installing
-do the same as down the other end
-cut a sliver out of the inside of the weather board so the flashing can be pushed through and sit flush
-once pushed in, sit the 2 bits of timber (nailed together for the window to sit on)
-when sitting flush, pack out 10mm, drill and nail with clouts
Flashings are designed to catch the moisture from under the window and stop water from sitting and creating mould/dampness. Every window that had etapan under it had to be packed out 10mm off the timber. Other windows had to sit flush. Silicone was put in the corners of the flashings to make them air tight and make sure no drafts come through because you can loose alot of heat through your windows themselves. Clouts are used because of there flats heads and sit hard against the tin. Windows started to be installed, rippings were cut and nailed on the outside, flush with the top of the windows sill.
